There thousands of causes for anxiety, but a trigger could be the coffee we drink. One thing I noticed after I stopped drinking caffeinated coffee was my anxiety decreased. I didn't put two and two together till I saw research and studies that caffeine can actually cause anxiety symptoms.
Caffeine, the beloved stimulant found in coffee, tea, energy drinks, and even certain medications, is a daily ritual for many. It helps kick-start the morning, keeps us alert through long workdays, and can be a comforting part of social interactions. However, despite its many benefits, there is growing evidence that caffeine may be a hidden culprit behind anxiety symptoms or might be exacerbating existing anxiety. In this post, we'll explore the research on how caffeine affects anxiety, the amounts that can trigger symptoms, and how reducing caffeine can potentially bring relief.
The Relationship Between Caffeine and Anxiety
Caffeine is widely celebrated for its stimulating effects, but what exactly happens when we consume it? Caffeine blocks adenosine receptors in the brain, preventing drowsiness and promoting alertness. While this can be beneficial in moderation, high intake of caffeine can lead to a state of "caffeinism," which is marked by symptoms that mirror anxiety neurosis. These symptoms include:
- Nervousness
- Irritability
- Tremulousness (shaking or trembling)
- Insomnia
Evidence from Studies
Numerous studies have shown a clear link between high caffeine consumption and increased anxiety symptoms. For example:
- Greden (1974) highlighted that high intake of caffeine could produce anxiety-like symptoms, such as nervousness and irritability.
- Bruce et al. (1992) found that caffeine induced anxiety and physiological arousal, especially in individuals with pre-existing anxiety disorders.
- Alsene et al. (2003) and Bruce et al. (1992) observed anxiogenic effects with caffeine doses as low as 150 mg, with more significant effects at 250-500 mg.
- Greden et al. (1978) reported that individuals consuming 750 mg or more per day experienced greater anxiety and depressive symptoms compared to moderate and low consumers.
How Much Caffeine Is Too Much?
Understanding the threshold for caffeine consumption is crucial for managing anxiety. Research suggests that anxiogenic (anxiety-producing) effects can begin at doses as low as 150 mg, with significant anxiety observed at 250-500 mg. To put this in perspective:
- A typical 8-ounce cup of coffee contains about 95 mg of caffeine.
- An energy drink can contain anywhere from 70 to 200 mg per serving.
- Certain medications, especially pain relievers and cold medications, can also contain caffeine, contributing to overall daily intake.
Reducing Caffeine to Manage Anxiety
The good news is that reducing caffeine intake has been shown to alleviate anxiety symptoms in many cases. This can be particularly effective for individuals who are sensitive to caffeine or have pre-existing anxiety disorders.
Key Findings
- Bruce & Lader (1989) found that patients with anxiety disorders who abstained from caffeine showed significant improvement in their symptoms.
- Vinader-Caerols et al. (2015) highlighted that individuals sensitive to caffeine experienced fewer anxiety symptoms when they reduced their intake.
Practical Tips for Reducing Caffeine
